CLAMP FOR ANGLE-IBQN POSTS AND THE LIKE.

Specification of Letters Patent.

Patented J? an. its, 1915.

Application filed August 4, 1913. Serial No. 782,922.

To all whom it may concern Belt-known that I, HERBERT E. A'romsori, a subject of Great Britain, and a citizen of the Dominion of Canada, residing at Lincoln, in the county of Lancaster and State of Nebraska, United States of America, have invented certain new and useful Improvements in Clamps for Angle-Iron Postsand the like, and have described the same in the following specification, illustrated by the accompanying drawings.

The class of angle-iron posts and the like which are intended by these terms in the above title of my invention, includes every metallic post or pole which hasthe general form of angle iron and is erected for use by planting the point or foot of the same in the ground. This class accordingly includes angular fence'posts and all those typical posts which are the subject of Letters Patent No. 13,202, which were reissued to me February 14, 1911, for telegraph and telephone posts.

The present invention relates to means for engaging a post of this class either for the temporary purpose of protecting the top of the post while its point is being driven into the earth or for the permanent purpose of attaching to the post a brace, a guy, a swinging gate, or any other desired object either movable or stationary.

It is the object of the invention to apply to the post a means of attachment which is easily and firmly securable thereto at any desired height above the ground, and easily detachable therefrom; to prevent the top of the post from becoming bruised, battered, bent or buckled, by blows or pressure administered from above by a sledge or other means for the purpose of driving the point of the post into the soil; and in general to provide the post with superior means for transmitting to the post the power by which it may be driven into the ground, and with superior means for attaching to the post all necessary guys, gates, braces, etc.

To accomplish these objects I incorporate in my improved clamp an angular sleeve engaging the outside of the post, and an angular core, or key, engaging the inside of the post and of the sleeve.

In the accompanying drawings, which illustrate the best manner in which I have contemplated applying the principle of my invention, Figure 1 is a side elevation of an angle-iron post which is provided with three clamps constructed in accordance with these principles. Fig. 2 is a rear elevation of the same. Figs. 3 and 4c are details in perspective. Fig. 5 is a rear elevation of a partly assembled structure similar to Figs. 1 and 2.

in Figs. 1 and 2 the post 1 occupies an upright vertical position partly above and partly below the surface of the ground 2, and comprises the integrally united side plates 3 and 4, forming an angle with each other and severally tapering from the bottom to the top. The clamp 5 on the top of this post, comprises the sleeve 6 and the key 7 which are best seen in Fig. 5. This sleeve has duplicate side plates 8 forming an angel with each other and integrally united at the front of the sleeve; it has also one or.v more bars 9, orcross connections, uniting these plates at th ir separated edges behind. Being triangular in cross section, and preferably tapering slightly from bottom to top internally, and being provided at the top with the integral cap 10, this sleeve fits slidlngly over the top of the post and of the key 7. This key, being trough-shaped has duplicate side plates 11 integrally united at one edge, and preferably is slightly tapering externally to fit into the top of the post. It is closed at the top by an integral cap 12 projecting slightly beyond the sides of the key and fitting within the sleeve 6. This key is fitted to be inserted in the top of the post and to move downward therein till stopped by the contact of the cap 12 with the top of the post in the position shown in Fig. 5. After the key has been placed in the position last indicated, and after the cap 10 has been pushed down into contact with the cap 7, the post is operatively driven into the ground, as shown in Figs, 1 and 2, by successive blows delivered upon the top of the cap 10 and transmitted to the post by the cap 7.

The clamp 13 on the post 1, similarly comprises the sleeve 6 and the key 7 which are shown separately in Figs. 3 and 4: respectively. This key differs from the above described key 7 in having no part corresponding to the projecting portion of the cap 12, and in having no abutment against the end of the post for the purpose of driving the latter into the ground. The sleeve 6 differs from the above described sleeve 6 in having no part corresponding to the de- M scribed cap 10. Internally it has aQcentral c tongue lifor contact with the inside of the not shown in the drawings and with a V bracket 16 for other purposes of attachment.

The clamp 17 is a duplicate of the clamp 13 in an inverted position, and can be advantageously used in connection therewith for the support of a swinging gate having hinge pins occupying the holes 18 in the bracket 16. V I f 7 {claim as my invention v g 1. A clamp for a tapering post of the specified class, comprising a sleeve which is slidingly adjustable thereon and has an inwardly directed tongue extending into the interior of the post, in combination with a trough-shaped key wedged between the outside of the tongue'and the'inside of the post.

, 21A clamp'for a post of the specified class, comprising a sleeve which is adjustable thereon and has an inwardly directed tongue extending into the middle of they post, in'combination with a trough-shaped.

key fitted internally to the outside of the tongue, and externally to the inside ofjthe post.

3. A clamp for a post ofthe specified class, comprising a sleeve slidableon the post and having a terminal cap, .in combination with a key slidable endWise in'the minal cap, in combination'with an angular tapering key which isv slidable endwise in" the post and has a stop cap outside the post" r and in the pathof the, terminal cap. 7
